Sudoku Xtra 24
Feb 9th
Sudoku Xtra 24 is now finally available! It’s packed with 130 puzzles of a wide range of types, including a huge variety of sudoku variants.
This issue I’ve included a very wide range
of variants, including some new ones such as Two-grid Interconnected Sudoku, Mystery Multiple
Sudoku and Blackout Sudoku. Meanwhile I’ve made an effort to include all of the most popular
variants as requested by readers, such as Consecutive Sudoku, Inequality Sudoku, Odd/Even
Sudoku and of course many more.
If there’s anything you’d like to see in a future issue
This issue I’ve included some new sudoku types such as Two-grid Interconnected Sudoku, Mystery Multiple Sudoku and Blackout Sudoku. I’ve also made an effort to include all of the most popular variants as requested by readers, such as Consecutive Sudoku, Inequality Sudoku, Odd/Even Sudoku – and of course many more.
There’s also a range of non-sudoku puzzles, including Light-up/Akari, Hashi, Slitherlink, Battleships, Skyscrapers, Calcudoku, Futoshiki, No Four in a Row, and more!
It’s available either as a PDF to print yourself (every page is self-contained, so you can print only the pages you want), or as a professionally-printed book direct from Amazon – there are links for all of these on the Sudoku Xtra site.
101 Giant Sudoku series
Jul 29th
I’ve recently launched a new series of ‘101 Giant Sudoku’ books, to cater for those who like their Sudoku to be considerably larger than normal!
You can see the entire series at PuzzleBooks.org (scroll to the bottom) or visit Amazon and search for “101 giant sudoku”.
There are currently 12 books in the series: 14×14, 15×15, 16×16, 18×18, 20×20, 21×21, 22×22, 24×24, 25×25, 28×28, 30×30 and 36×36.
The larger puzzles work just as you’d expected, so in Sudoku 36×36, for example, you must place 0-9 and A-Z into every one of the 36 rows, 36 columns and 36 6×6 boxes!
These puzzles are designed so they don’t need any advanced logic – just scan the rows and columns and boxes to see what’s missing and what can fit where.
All of the puzzles are designed with attractive 8-way symmetry patterns.

Sudoku Xtra 18
Mar 28th
The 18th issue of Sudoku Xtra is now available, either pre-printed or as a downloadable PDF. It’s designed so each page can be printed separately, so you need only print the puzzles you want to try, and all of the puzzle content is in black and white.
This issue features 130 logic puzzles in a wide range of designs and sizes, from 5×5 right up to larger than 30×30. Puzzle types include Yajilin, Heyawake, Nurikabe, Masyu and more of the Windows puzzles introduced in the previous issue, plus an enormous range of different Sudoku variants including many seen on this blog.
There’s also a packed Community Puzzles Section featuring content from the world’s best puzzle authors, such as David Millar’s awe-inspiring Knighted Samurai Shape Sudoku through to more of Vexus Puzzle’s delightful route-finding Tiktaka.
Sudoku Xtra 16 and Sudoku Xtra 17 have also been published since I last updated this blog, so head over to the Sudoku Xtra magazines page for more details.

Sudoku 16×16 Volume 1 – Sudoku Xtra Specials
Feb 15th
A book of just 16×16 Sudoku is now available both for download or in pre-printed form from Lulu.com or Amazon.com (with free delivery in some cases).
I’ve had lots of requests for a book like this over the past couple of years, so I hope if you’re one of the people who’ve wanted something like this that the book meets your expectations! All of the puzzles have nice symmetry, and the difficulty level is set such that you won’t need to make lots of fiddly pencil marks in the grid (or indeed any pencil marks at all, if you don’t want to).
It’s printed on large paper (A4 at Lulu, 8″x10″ at Amazon), with just one puzzle per page, so you’re getting the puzzles at a comfortable size for solving. Full solutions are included, and with 50 puzzles it’s going to take you a long time to solve them all!
Please feel free to post any comments here, or head over to Sudoku Xtra and take a browse on the discussion forums – and maybe join in!
Sudoku Xtra Specials: Sudoku 25×25 Volume 1
Feb 5th
I’ve had many, many, many requests over the past years for a book of giant 25×25 Sudoku puzzles, so I have now finally made just such a book available!
Right at the moment it’s only available in printed form, but I’ll have download copies available in the next couple of days – as soon as I’ve added a purchase mechanism to SudokuXtra.com in fact!
I’ve decided that I’m going to make a series of similar books of particular requested puzzles, all of which will be branded as “Sudoku Xtra Specials”. In this way I can stay organised by keeping all of my download/printed content under the ‘Sudoku Xtra’ heading. It means that you’ll always be able to find all of my new content in one place, without searching around my various sites.
This book is probably the nicest collection of 25×25 puzzles you can find, if you’re a fan of such things. Every puzzle has really nice 8-way symmetry – having noticeable patterns in puzzles like this is pretty unusual, and it can help with the solve too. Just as in my magazines, I’ve thought about what’s sensible in a puzzle like this so they can all be solved without needing pencilmarks. How exactly would you go about making A-Y pencilmarks in each individual square anyway?!
If you get hold of it please do let me know any thoughts you have on it. In the same way as for Sudoku Xtra magazine, it’s designed to be printed at home on either an all-together or a page-by-page basis. And if you get a pre-printed version from Lulu or Amazon.com (already complete but waiting on listing now) then it’s on a large A4 (Lulu) or 8″x10″ (Amazon) page, so there’s plenty of room to write in the solutions.
If there are other books of puzzles you’d like to see, please let me know in the comments here or on the Sudoku Xtra forums – feel free to repeat any requests you’ve made before! Next up is 16×16 Sudoku but after that it’s all open. I was thinking of doing Inequality Sudoku third, but what do you think?
Barnes & Noble
Feb 4th
I was interested to spot that Barnes & Noble (in the US) are now selling one of my self-published books – Killer Sudoku: 100 easy to hard puzzles and how to solve them.
So if you’re in the US and fancy getting hold of a copy (they get really hard by the end!) then there’s now another way to buy it. You even get 10% off if you’re a member.
